Warren was sent to the Chicago Cubs in the same deal that brought over Starlin Castro.

From a “WAR” perspective, Warren can be replaced by virtually anyone. But when you look deeper into how valuable this swing man was for the Bombers, you’ll realize it’s a tall task.

Warren pitched in 131.1 innings, going 7-7 with a 3.29 ERA in 17 starts and 26 relief appearances for the Yankees last season. No one will be talking about his 2015 season when we’re all gone, but his value was undeniable.

For a rotation that struggles with health and consistency last year, Warren was able to make spot starts if they needed days off, and provide long relief.
